Paper Title
Effects of Pre Storage Heating and Egg Position During Different Storage Period on Hatching and Productive Performance of Broiler Chicks

Abstract
Nine hundred Ross-308 broiler breeder eggs were used and hatched at Lawlaw Hatchery in Sulaimani in Bazean region during 12/11- 04/12/2011; eggs were hatched at (37.4 C◌ with 70- 75% relative humidity),chicks at the first week were reared and treated as one group. At the beginning of the second week chicks were distributed randomly into nine treatment groups, 3 replicates per treatment group with 15 chicks/ replicate for each treatment. The experiment was conducted in the poultry farm of the Directorate of Agricultural Farms in Faculty of Agricultural Sciences / University of Sulaimani started on 28/10/2011 and finished at 14/01/2012. The aim of the experiment was to assess the effect of different storage periods, pre- storage heating duration and egg position during storage period on post-hatch productive performance and carcass quality of broilers hatched from eggs purchased from local commercial hatchery in Sulaimani. The results revealed that egg storage period for one week was significantly (P<0.05) better than two week storage period in feed consumption, live body weight, weight gain and feed conversion ratio (FCR). Also there were no significant differences between three hours or six hours pre-storage heating groups at most ages for the above traits except 3h. group showed significantly (P<0.05) better (FCR) at the last weeks of age, while there were no significant effects on the above traits by egg position factor during storage period at most ages. Furthermore, live body weight and dressing percentage during marketing ages (32, 35, 38 and 42 days) were significantly (P<0.05) affected by egg storage period. Key Words- Heating, Storage Period, Hatching, Productive Performance, Broiler Chicks.
